33. CPVE Client Quality of Service (QoS) - DSCP
Two high-level approaches:
1. Local packet marking
2. Create identifiable traffic streams edge devices mark DSCP, either by
sending media on specific port ranges, or via Medianet
Local Packet Marking (depends on OS platform)
Windows 7
Does not allow applications to mark DSCP (unless Network Config Ops group
member)
Windows XP
Jabber will mark packets using an API from windows 2000

34. QoS and Trust with CSF Desktop Clients
 Windows 7 QoS and Security Model
 Windows 7 user mode apps cant set QOS / DSCP markings.
 Recommended to use the QOS Policy Engine via AD Group Policies
 Using Group Policy for CSF Clients (Jabber, CUCI-LYNC)
media ports can individually be marked with correct DSCP value
 Alternative switch configuration
 CSF uses different port ranges for different types of media
 Centrally administrated port range configuration from CUCM, lower half utilized
for audio and upper half utilized for video streams

35. Metadata for End to End Classification
Voice communication between Marylou and John
Voice communication started with application ―X‖ This flow has a DSCP = EF
Packets has DSCP=EF This flow contents RTP Voice
I know lots of information from the application
that I’m not going to send to the wire
John
Marylou
This packet has a DSCP=EF
This packet comes from Fast1/0
This packet comes from location ―Desk1‖
This packet comes from user ―Marylou‖
• How to enforce a consistent network policy when classification are not available along the path ?
– Eg: Rule: Prioritize Voice communication from Marylou to John ?
• Endpoint can provide information not available or visible on the wire

38. Call Admission Control (CAC)
#CiscoPlusCA

39. Call Admission Control - Mandatory?
• Over-provisioning for Unified
Communications media is extremely
difficult
• UC media traffic cannot be
―squeezed‖ or delayed (it is
inelastic), so congestion control
cannot be used
• Different policies need to be applied
to different types of calls

 Support different policies / multiple
 Easy to deploy applications and instances
 Handles different policies (per media  Optimal use of resources (accurate
type, per calltype, per user) tracking of path and bandwidth, reacts to
network failures/changes)
 Unaware of network state
 Preserves user experience

41. Admissions Control and QoS Synchronization
• CAC model needs to reflect QoS / Network reality
• Same-class application DBs must add up to or less than
class bandwidth

Application Class PHB Cisco Video Applications
Control Congestion Avoidance

Real-Time Interactive CS4 Required (Optional) PQ Cisco TelePresence and CIUS Video
Multimedia Conferencing AF41 Required BW Queue + DSCP WRED Cisco CUPC / Video Telephony / EX / MXP

42. Admission Control Policy and Mediation
• Remember: Admission Control enables deterministic session
experience
• Simplest form of mediation is denying additional sessions
• Advanced forms may force renegotiation of existing sessions to lower
experience (lower bitrate, resolution, fps, no video etc.)

Video adhoc VC TP ad-hoc Scheduled Voice Voice

43. Session Level Bandwidth Modifier (CUCM 8.6+)
Specifies the max amount of bandwidth needed when all the media streams used
Typically this will be less than the sum of individual streams values (not all
streams have their maximum at the same time)
There are 3 Session Level Bandwidth Modifier values:
• b=TIAS:<bandwidth-value>
Transport Independent Application Specific Maximum (TIAS) bandwidth modifier is a bit-rate value. This value is the
max needed by the application (SDP session level) or media stream (SDP media level) without headers.
• b=AS <application Specific>
Application Specific maximum bandwidth is dependent on the application's notion of maximum bandwidth .
• b=CT <conference Total>
Conference Total gives a maximum bandwidth that a conference session will use. Its purpose is to decide if this
session can co-exist with any other sessions.

44. Adaptive Video and Call Admission Control
• Video application automatically adapts (adjusts bitrate) to available
bandwidth
– Used with admission control mediation
– Video Escalation / De-escalation
• If used without admission control, place in best effort QoS class
– Watch for fairness and other-traffic starvation
– Keep business critical traffic separate

Video adhoc VC TP ad-hoc Event Scheduled

45. CVPE Media Resilience – Bandwidth Adaptation
Packet loss reported by remote endpoint via RTCP Receiver Reports (RRs) and
CPVE adjusts bitrate accordingly
Two types of Bandwidth Adaptation
1. Static Network Adaptation – pick best starting rate to transmit new call and best possible initial
receive parameters to influence incoming bandwidth
2. Dynamic Network Adaptation - adjust the transmit rate during call to maximise bandwidth use when
needed but avoid congestion
Reducing the configured sending rate:
There are 2 phases of Downward Adaptation
1. Startup Phase - The first 10 seconds since receiving the first RR
• Minimum of 2 RRs received reports losses
2. Steady State
• The network is classified as Consistently Lossy and
• The most recent observation has significant packet loss (i.e. > 1%)
Room based Scheduled
TP ad-hoc Event

46. Media Resilience – Bandwidth Adaptation
Note for downspeed:
• Bitrate is never reduced if the network is classified as Burst Lossy or Lossless
• A new reduced bitrate is never lower than 128 kbps
• Subsequent bitrate reductions (if required) are spaced by minimum of 10 seconds
CPVE Increases the configured transmit rate if - and only if –
• The network is classified as Lossless
• The current configured sending rate is lower than the allowed maximum media bandwidth available for the session
If the above is satisfied, increase bitrate by MAX (15% of current send rate, 64 kbps)
Bitrate increases (if criteria met) are separated by 20 seconds minimum.
CPVE will also adjust the encoding video width and height that are supported by the current video capture device
according to the newly adapted send rate.
Important Note: The above behavior assumes the following:
• The other endpoint supports RTCP and sending of RTCP RRs
• The other endpoint sends RTCP RRs every 5 seconds
If either of these are false, the timing and behavior of the above will be significantly different, and BW adaptation
may not work at all

55. Cisco Centralized Key Management (CCKM)
• With 802.1x authentication recommended to implement CCKM for fast secure roaming
• 802.1x introduces delay during roaming with requirement for full re-authentication
• CCKM centralizes the key management and reduces the number of key exchanges.
• With CCKM roaming times can be reduced from 400-500 ms to less than 100 ms, hence
the transition time from one AP to another will be transparent to the user
• CCKM can be utilized with the following security combinations
802.1x Type Key Management Encryption
EAP-FAST WPA2, WPA AES, TKIP
PEAP WPA2, WPA AES, TKIP

56. WLAN Admission Control and QoS
• Admission control grants clients access on per-WLAN (SSID)
• This is typically done in one of two ways
– Load – number of calls based on channel load
– TSpec – based on a host of additional parameters
• Wi-Fi Multimedia (WMM) 802.11e’s Traffic Specification
(TSpec) takes much more than load into account
– Clients request admission based on: traffic priority (access category),
power save, mean data rate, frame sizes, min PHY data rate

57. Wi-Fi Multimedia (WMM)
• What is WMM?
 supplement to 802.11 MAC layer
 Allows Diff-Serv QoS by creating four queues, called Access Categories
 Access Categories access channel via EDCA (Enhanced Distributed Channel
Access), an enhancement of the existing DCF (Distributed Coordination Function)
• What does WMM add?
 Uplink frames are marked with 802.1p CoS
 Prioritized access for uplink traffic
 ACM flag allows uplink access categories to be enabled/disabled

58. 802.11e / WMM Media Access Classifications
• Separates traffic types in to 4 QoS access categories (AC)
• Background, Best Effort, Video, Voice
• These 4 ACs also have unique delay and random back off characteristics for
accessing the RF channel (EDCA)
Applications
Background Best Effort Video Voice
Internal
Collision
Resolution

59. Quality of Service (QoS) with Wireless
To ensure proper queuing, use the following suggestions:
 Ensure WMM is enabled in SSID config.
 Enable network DSCP or configure QoS policy to set the DSCP values
 Enable the ―Platinum‖ QoS profile in the SSID configuration when using
Cisco Unified Wireless LAN Controller technology.
 QoS policy needed for Cisco APs in autonomous (standalone) mode

Video AF41 (34) 4 5
Call Control CS3 (24) 3 4

60. SIP Based QoS and CAC
• SIP Based QoS (WLC code stream 6.0)
• Intercept and snoop SIP traffic (AP: Upstream, WLC: downstream) to
determine voice session and set QoS
• RFC 3261 compliant client
• SIP Based CAC (WLC code stream 7.0)
• Enable the network to roam voice session between APs based on
available bandwidth
• Feature is applicable to SIP phone w/o TSPEC
• Bandwidth parameters are configured manually on per session basis

63. Data Rate Config and Wifi Channel Utilization
To increase channel utilisation on WLAN, data rates in use need to be faster.
–To do this the lower data rates must be disabled thereby forcing the use of the faster data rates that
are enabled for WLAN
– Recommended to disable rates below 12 Mbps for best results
• 802.11b data rates should only be enabled if legacy clients exist in 2.4 GHz
• Recommended use 5 GHz for CIUS / UC devices if legacy devices in 2.4 GHz
802.11 Mode Mandatory Data Supported Disabled
Rates Data Rates Data Rates

(MCS 8 – MCS 15)

64. WLAN Cell Design
Ch 36 Ch 149 Ch 56 Ch 48
Ch 52 Ch 44 Ch 161 Ch 60
 Cell edge should be -67 dBm, which is the minimal required signal strength for UC
 At least 15-20% overlap of adjacent cells
 Recommended to have dual APs available with adequate signal in critical use areas.

65. Call Capacity
• Ensure network is designed to accommodate desired call capacity
• Cisco APs can support up to 27 bi-directional voice streams for both
802.11a and 802.11g at 24 Mbps or higher
• Call capacity can be reduced if using Coexistence
• Coexistence = 802.11g/n + Bluetooth WLAN
Controller
• Use of 802.11b is NOT recommended
